For this interim report, the committee was charged with assessing the technical merit of the proposed R&D in the near term. This report does not NOTE: This appendix is a reprinting of the main text of the committee's interim report, A Preliminary Assessment of the Profuse of Continued R&D into an Electrorr~tallurgical Approach for Treating DOE Spent Fuel (National Research Council, Washington, D.C., 1995~; also included is Argonne National Laboratory's draft "Proposal for Development of Electrometallurgical Technology for Treatment of DOE Spent Nuclear Fuel."

Dunng this meeting the committee was briefed by DOE representatives and was provided with relevant technical information in the form of presentations Mom and discussions with technical experts, including representatives from the Argonne National Laboratory as well as scientists from Westinghouse Hanford Co., Westinghouse Savannah River Co., amd Sandia National Laboratones. In addition, the committee received input from representatives of several Interested public citizens groups on the subject.

The committee believes that prior to malting a final decision about widespread implementation of the ANE electrometallurg~cal technology for treating DOE spent Mel, it is essential that the DOE deteIInine how the electrometallurg~cal technology, and over treatment technologies, fit into its overall strategy for spent fuel disposal and the closely related strategy for the management of high-level and transuran~c wastes.

The electrometallurgical treatment technique, developed by the Argonne National Laboratory, appears to have great potential for application in the treatment of the collection of DOE spent nuclear fuel types for ultimate disposal. This process is applicable in its current stage of development to over 90% of the DOE spent fuel inventory and offers the advantages of a simple, compact system that is both economical and technically sound.

The fission products are recovered separately and immobilized in stable high-level waste forms, one metal and the other mineral, for ultimate repository disposal. There are a number of incentives for the electrometallurgical treatment of the DOE spent fuels.

PROPOSED DEVELOPMENT PROGRAM -1 ~Or- A Argonne National Laboratory proposes to complete the development of the electrometallurgical treatment technology for application to selected DOE spent nuclear fifed types. The proposed program is directed toward a timely demonstration of the feasibility of application of the electrometallurgical treatment technology to the treatment of DOE spent fuels.

The approach will be to demonstrate application of electrometallurgical treatment to tow-enriched zircaloy-cIad or aluminum-cIad metallic uranium fuels, first with unirradiated fuels and then on a limited scale with irradiated fuels in the Fuel Cycle Facility. Established electrometallurgical flowsheets will be tailored to provide an efficient process for treating these spent fuel types, with initial emphasis on developing and demonstrating a process for rapid electrolytic dissolution of fuel materials from intact or damaged fuel elements.

Collected sludge samples will be treated in the Fuel Cycle Facility or the Hot Fuel Examination Facility to provide a hot demonstration of the process. Major milestones for the FYI995-FYI997 period are as follows: Major Milesior~es, FY-1995 (2)

Testing of a zeolite column system will be carried out to verify the kinetics of fission product adsorption, leading to a cold demonstration of the waste form production process at the ~ kg batch size. A hot demonstration of the production of the mineral waste form will be conducted as soon as sufficient waste material is available from demonstration of the electrometallurgical treatment processes.

The timing of the development program is very demanding, directed toward completion of the work so that a meaningful base of experience is at hand by the end of FYI998 to permit a reasoned decision on the application of the electrometallurgical treatment technique to the treatment of DOE spent fuel. Argonne National Laboratory is not proposing the shipment of spent fuel inventories to any particular site for treatment, but instead proposes to support the implementation of the technology at the sites where the spent fuel is now stored.
